CE-CIREAM DISHER.

To all 'who/Ht t may; concern;

Be it .known that l, ,RAYMOND B. GIL- cnms'r, a resident of Newark, inthe county of Esseri: and State olf New Jersey, have in- 'rented certainnew and useful linprovee lments in lee-Creane Dishers, of which thefollowing is a full, clear, and exact description.

The invention relates to ice-cream dishers anddesigns to provide asimple and ellicient device in which provision is niade for convenientlyand quickly removing the scraper and for cleaning the several parts.

The invention consists off the several noyer A features hereinafter setforth and more pan tieularly defined by claims at the conclusion hereof.

Fig. '2 is a central longitudinal section.through the bowl. Fig. 3 is a section taken on line 3-3 ot `Fig. l. Fig.4 is a section "to remove the icecream from the bowl.

ing :2l is formed in bowl l1 and traine l0 to support the spindle andscraper inter-- mediate the trunnionl9 and bearing il. journal isprovided on a spindle -which is adapted to lit into the open bearing 2l.This journal 22 is removably held in bearing 21 and is removable withshaft lll. The overhanging portions Q3 of bearing serve to hold journaland shaft la in said bearing. Journal :22 is formed on a sleeve which isslidaoly held on shaft la and is normally pressed toward and against theinner end of scraper 13, by a. coil-spring 25 which encircles shaft lland engages a collar 26 lined on the shaft and a shoulder 27 on thesleeve. By means of this sleeve and slidahle connection., the journal 22may be drawn out of bearing 2l so that when trunnion i9 is sprung out otits bearing 20,

shaft 'll may be shifted longitiulinally to withdraw the inner endthereof from bear- Ying 9, and then the opening in bearing 2l willpermit shatt le to be ren'ioved troni said hearing. lllhen the sleeve:2l is moved inwardly, as indicated by dotted lines, Fig. i?, andtrunnion 19 is released the shaft may be shifted longitudinally todran'v its inner end out of bearinff S) and then the shaft will beentirely diseonnected from the handle.

ln Fig. G is illustrated a. modified iorni of the invention, in which ajournal 30 fixed ou shaft il and is held in the open hearing In thisforni of the invention, when trunnion 19 is sprung` out of its hearingin the loowl, the ishaft ll and its journal 30 may be shiftedlongitudinally so the latter will clear the open bearing` and then theshaft may be removed from the open bearing, it being understood thatwhen journal 30 is in the position indicated in dotted lines of Fig. 6,the inner end of the spindle cai ried by bearing` 9 will loe Withdrawntherefrom and that the scraper in the bowl serves to hold theshaft'against longitudinal movement and in its bearings.

ln practice it has been ound,`that in the type of device exemplified, inwhich the shaft la extends inwardly o a point adjacent grip l2, theshaft is sometimes sprung as a. result of beine' struck against an ice'cream can or tub', and to overcome any possibility of bei-ng sprung., anabuti'nent 3l is formed on the handle. This abutment disposedintermediate the bearings for the -shaft and elise-,tively serves 'teprevent the shaft from beingspiung toward the frame. ln practice it hasalso been found, that greatest power is required during the initialmovement of the scraper, hecause'fthe scraper tends to move the entirebodyldlltmaterial in the bowl, rather than to act as a knife whilepassing between the bowl and the ice-cream, and that, after the icecream has been partially removed from the bowl less force is required toeffect the movement of the operation. To meet these diihculties and torender the device more easily operable, the gear-connections betweenlever 1T and scraper shaft 14 is constructed to operate differentially,that is, to apply greater power to the scraper during its initialmovement. As illustrated in Fig. 4 pinion 15 is eccen-y trically securedto and mounted on shaft 14 so that in norm-al or starting position, thegear will have a long radius or leverage, and a relatively decreasingradius and leverage during the remainder of the stroke.

The rack 16 is inclined or formed to cornpensate for the variation inradius of the operative port-ion of pinion 15. Resultantly during theinitialmovement of finger-piece 18 greater force will be applied andgreater leverage will be attained, as necessary to initially remove theice-cream in the bowl, and thereafter the leverage will decrease as theresistance of the cream to the scraper decreases.

The invention is not to be understood as restricted to the details setforth since these may be modified by the skilled mechanic within thescope of the appended claims without departing from the spirit and scopeof the invention.
